Extraction of Low Reactivity Metals Metals and Nonmetal

Extraction of Low Reactivity Metals Metals like copper, mercury, silver and gold are less reactive. Metals at the bottom of the reactivity series can be obtained by heating their compounds. For example, when cinnabar (HgS) is heated in a furnace, it is reduced to metallic mercury. Metals in the middle of the series like zinc, iron, nickel, tin, lead, etc., are reduced by a chemical reducing agent like carbon
